Electronic bridge process in 229Th^+

Abstract

We have studied the effect of atomic electrons on the nuclear transition from the isomeric {229m}Th state to the ground {229g}Th state in {229}Th+ due to the electronic bridge process. The exact value of the nuclear transition frequency is unknown so far; therefore, we have developed a formalism that can be used for any nuclear transition frequency. We have calculated positions of several high-lying even-parity states which are not presented in experimental atomic spectra databases. We have found their energy levels and g factors.

Minor corrections in the text and Table II are made. The reference journal is added.
